Abstract
Shake closed vibration sieve of a kind of multilayer with self-inspection early warning more, comprise screen box, frame, transmission device, drive motors, the crossbeam of screen box is fixed in frame by being positioned at four jiaos of auxiliary vibrating springs that arrange below crossbeam, is glued with the detection probe of low frequency EDDY CURRENT main frame at the clad outer surface of crossbeam outer wall parcel; The below of screen box one side and screen box is equipped with vibrator, and vibrator connects drive motors by transmission device.The utility model is installed two-layer vibration screen with multiple vibrators, realize the meticulous screening to material, screening precision is high, meet the screening of different size material, screening efficiency is high, has increased case lid on screen box, allows screen box form a closed working space, reduce noise, and solved dust pollution question; Adopt low frequency EDDY CURRENT vibratory sieve crossbeam fatigue crack, the clad on the penetrable crossbeam of low frequency eddy current is the crackle of crossbeam to be detected, and not only cost is low, and speed is fast, and detects reliably, thereby reduces loss.
Description
Technical field
The utility model relates to a kind of vibratory sieve, is specifically related to shake closed vibration sieve of a kind of multilayer with self-inspection early warning more.
Background technology
Vibratory sieve is that sieve nest utilizes vibration characteristics to complete a kind of vibrating mechanical equipment to techniques such as the sorting of material, classification, de-mediated and dehydrations, is widely used in the occasions such as metallurgy, coal, mine, water conservancy and building materials.Taking vibration screen for mineral as example, vibration screen for mineral is used for raw coal carry out classification, medium recovery, dehydration and remove discarded object etc.Vibratory sieve is one of key equipment during coal separation is produced; and crossbeam is the vital part of vibratory sieve; play a part to support and protection; and in the course of work, bear for a long time the effect of screening materials carrying gravity, impulsive force and alternation exciting force due to crossbeam; so fracture of girder is the fault that often can occur in actual production, and its safe operation is extremely important to colliery washing safety in production.
Utility model content
The deficiency existing for above-mentioned prior art, the purpose of this utility model is to provide a kind of multilayer with self-inspection early warning closed vibration sieve that shakes more.
The technical solution of the utility model is: shake closed vibration sieve of a kind of multilayer with self-inspection early warning more, comprise screen box, frame, transmission device, drive motors, it is characterized in that, the crossbeam of described screen box is fixed in frame by being positioned at four jiaos of auxiliary vibrating springs that arrange below crossbeam, is glued with the detection probe of low frequency EDDY CURRENT main frame at the clad outer surface of crossbeam outer wall parcel; The below of screen box one side and screen box is equipped with vibrator, vibrator connects drive motors by transmission device, described transmission device comprises main shaft, eccentric flange and elasticity movable coupling, drive motors connects one end of main shaft, the other end of main shaft connects eccentric flange, eccentric flange is arranged on a side of elasticity movable coupling, and the opposite side of elasticity movable coupling connects vibrator; Directly over screen box, be provided with case lid, case lid one side is provided with feeding mouth, and the below of screen box and be positioned at the side that feeding mouth is relative and be provided with discharging opening is provided with the vibration screen that two layers of mesh hole size differs in screen box.
Advantage of the present utility model: 1, the utility model is installed two-layer vibration screen with multiple vibrators, realize the meticulous screening to material, screening precision is high, meet the screening of different size material, screening efficiency is high, has increased case lid on screen box, allows screen box form a closed working space, reduce noise, and solved dust pollution question; 2, adopt low frequency EDDY CURRENT vibratory sieve crossbeam fatigue crack, the clad on the penetrable crossbeam of low frequency eddy current is the crackle of crossbeam to be detected, and not only cost is low, and speed is fast, and detects reliably, thereby reduces loss.
